Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed August 20, 1914. Serial No. 857,758.

To all whom it may concern:

Be it known that I, IVILLIAM STUEBING, Jr.,- a citizen of the United States, residing at-thecity of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and-useful Improvements in Trucks, of which the following is a specification.

My invention belongs to that class of trucks in which powerful mechanical devices are employed to assist in lifting the load to be carried: thus the load can be readily loaded or unloaded; and in connection with which supplementary platforms are employed, which have been previously loaded or upon which goods have been placed regularly in thecourse or process of manufacture.

The object of my invention is to produce such a truck which shall be cheap of manufacture, simple in construction and highly efficient in use, which shall have less parts, willnot readily get out of order and which shall have a higher lift than the trucks of this class.

It consists essentially in providing a frame or body portion and an elevating platform working up and down thereon, to lift or lower the load. a series of pawls and levers being the means for elevating and lowering the platform. The handle of the truck is so swiveled that it can be turned around in a circle. either when the truck is empty or loaded, so that the truck can be. pulled at any angle. The handle must first be pulled down to raise the platform and put up to lower it, in order to force the operator to gain control of the load at all times, before raising or lowering the load. Its various features and advantages will readily become apparent from the following description.

In the accompanying drawing forming part of this specification, Figure (1), is a section on theline 11 of Fig. (3). Fig. (2), is a side elevation of the truck. Fi (3), is a plan view thereof, and Fig. (4 is a view of one of the supplemental platforms used with the truck. I

In carrying out my invention I provide a body orframe (1), madeof any suitable form and material and .a lifting platform (2), also made of any suitable form and material, the whole being mounted on wheels (3), two rear wheels and a. single swiveled front wheel.

On the frame (1), at the rear, on each side, I provide an incline (4) and at front and end an incline (5). Along the inclines (4), on the frame (1), and parallel to the incline, I provide guidestrips (6). On the platform (2), I provide inclines (7) adapted to engage and slide up and down on the inclines (4) and. also be engaged by the guide strip (6) so as to keep the platform (2) in proper contact relation with the frame (1).

On the platform (2) at the front part thereof I place a block or incline (8) which engages incline (5) on frame (1). The incline (8) is held in operative position and alinement on incline (5) by a screw (9), which passes through a slot (8) in incline (5) and then into the incline (8). The incline (8) is provided with two lugs (10), to which is secured, by a short shaft (11) a link hook, or pawl (12), adapted to be engaged by the pawl (13) which is pivotally mounted on the lever (14), at point (15).

Mounted on frame (1). on the short shaft (16), is a pawl (17), which is adapted to engage the tooth (18) on the pawl (12) when the platform (2) is in raised position. This shaft (16), (being the same shaft on which pawl (17) is mounted), also carries a short lever (20), which lever is used to release the pawl (17) from engagement with the tooth (18) of pawl (12), in order that the platform (2) may be lowered.

The front wheel (3) is mounted in a yoke (22), which is swiveled in the frame (1) by the swivel (23), so that the truck can be moved sidewise or other desired directions.

The handle (1%) is fastened to the upper part of the swivel (23), making it possible to guide the front wheel (3), and thus, the truck. The handle being thus fastened in the upper part of the swivel renders said handle on able of describing the arc of a circle in tie bands of the operator, as there is no'hindrance or bar to said motion in this construction. the truck with a maximum degree of efliciency, as I can turn it anywhere and in corners and small spaces, elevators, passageways and the like and force it to' travel at any angle. In using this style of truck, a multiplicity; of auxiliary platforms (21) are used. Thegoods or articles are either placed on these platforms during the process of manufacture or when they are finished, or placed This enables me to handle I lowered position as shown infFig. "'(2 is backed in under theplatform (21)"and1f it is desired to raise the platform (21) and its load, in order to move it to any given point or place, the handle (14:) is raised so that the'pawl (13) is brought into engagement with the tooth (19) on pawl "(12) ;'when this takes place the handle is lowered or brought forward and this movement-pulls the lifting platform (2)- forward and upward on the inclines (4-) "and (5) until the pawl- (17) engages the tooth (-18) on awl (12);the platform (2) isfnovv' up an the pawl (13) may be 'released 'leaving the )latforni in raised position as'shown in ig. ('1).

I-n lowering the load or platform (2), it is necessary to first bring the handle down asshown in Fig. (1;), thusallowing pawl (13) to engage the tooth (19)='on"pawl (12) and thus allowin' pawl (17) tube-released from contact witli thetooth (18) on awl (12), which is done byra'ising the ever (20), (which'is on the same shaft (16)- on which pawl (17 is'mounted),' and'then, as the handle is raised, the'loa'd or platform (2) is lowered'to'normal osition by the said platform- (2) sliding own on the inclines (4) and (5).

\Vhen the platformi (2) is elevated and held elevated by pawls (12) and (-17) the pawl (13) is thrown back on the handle'as shown by dotted linesin Fig. (1), thus forcing the operator to gain control of the load by dropping said pawl (13), if he'fdesires to lower the platform (2).

While I have described one specific form and construction of my track, it will readily become apparent that it is capable of considerable change and modification without departing from the spiritand principle of my invention, and I wish to be understood that such changes'and modifications will still fall within 'the'scopo of my invention.
